Re: Allen head vs. regular polepieces
Hex poles is a general term to identify the hex shape slot on the head of the screw. Hex and Allen are the same thing just a different name. The picture shows 2 different kinds of hex poles, hopefully this will help explain:
TOP RIGHT: cylindrical screw typically found in older Dimarzio's like Super Distortion, Super II, Super III, Dual Sound, I think the Evolution uses these also.
Technical name is actually called a
"SOCKET SET SCREW". The one shown there is a 10/32# x 1/2"
BOTTOM LEFT: the typical screw you find in any pickup as far as dimensions go outside of the type of head. Hex shaped slot instead of a flat slotted. Typically found in Dimarzios such as: PAF PRO, Double Whammy, Humbucker From Hell etc. Seymour Duncan uses these on the Full Shred, and 1 side of the Screamin Demon.
Technical name is actually called a
"SOCKET HEAD CAP SCREW". The one shown there is a 5-40 x 1/2"
